The legal status of anabolic steroids varies from country to country. In the ., anabolic steroids are listed as Schedule III controlled substances under the Controlled Substances Act , which makes the possession of such substances without a prescription a federal crime punishable by up to seven years in prison.  In Canada, anabolic steroids and their derivatives are part of the Controlled drugs and substances act and are Schedule IV substances, meaning that it is illegal to obtain or sell them without a prescription. However, possession is not punishable, a consequence reserved for schedule I, II or III substances. Those guilty of buying or selling anabolic steroids in Canada can be imprisoned for up to 18 months. Importing or exporting anabolic steroids also carry similar penalties.  Anabolic steroids are also illegal without prescription in Australia,  Argentina, Brazil, and Portugal,  and are listed as Schedule 4 Controlled Drugs in the United Kingdom.
There is little or no need to stack secondary drugs with finaplix. It does not aromatize. There is some concern as to finaplix being progestagenic, so should you opt to stack it with an aromatizable compound it may worsen potential gynocomastia so adding Nolvadex, to such a stack may be wise. But in itself or in a non-aromatizing stack this is not necessary. The use for post-cycle estrogen antagonists is limited as well, so Nolva or clomid to boost natural test will have little use. It is a very strong androgen receptor agonist however, so perhaps using some HCG after a cycle may help you retain more gains and prevent testicular shrinkage, but since HCG does increase estrogen that does reinstate the use of Nolvadex or clomid as well.
To strengthen the anabolic properties of testosterone, more than 100 synthetic steroid derivatives have been described for human purposes. The anabolic effect promotes protein synthesis, muscle growth and erythropoiesis. In clinical practice, substances with anabolic effect are needed to overcome various catabolic states. However, none of these compounds are devoid of androgenicity. Androgenic and anabolic properties of anabolic steroids cannot be totally separated. Therefore, it is more appropriate to use the term anabolic androgenic steroids (AAS).
